Gamepad input lag (delay between pressing a button and the action appearing onscreen) can make any game feel slow, unresponsive, or impossible to play — especially in FPS or racing games where milliseconds matter.
In this guide, you’ll learn:
- Why input lag happens
- How to reduce it on PC (Windows) and Android
- How to test if your gamepad is lagging (online)

What Causes Input Lag?
Input lag usually happens due to:
| Cause | Examples |
|---|---|
| Bluetooth interference | WiFi router nearby, metal desk, other Bluetooth devices |
| Bad controller cable | Loose USB cable, low data-quality cable |
| OS features | Steam Input, controller emulation layers |
| Low battery | Weak wireless signal causes delay |
| Browser or game engine delay | Games that don’t support the controller natively |
Fix Input Lag on PC (Windows)
1. Use a USB cable instead of Bluetooth
Wireless controllers introduce delay. A wired connection offers:
- Lower latency (0–3 ms)
- Stable performance
- No interference issues
If you must use Bluetooth, move to step 2.
2. Disable Steam Input (This fixes 80% of delay issues)
Steam adds its own controller layer, causing delayed response in games.
Fix:
- Open Steam
- Go to Settings → Controller
- Disable “Steam Input”
Additionally:
Per Game → Properties → Controller → Disable Steam Input
3. Update Bluetooth drivers
- Open Device Manager
- Find Bluetooth
- Right-click → Update drivers
Old Bluetooth drivers = delayed input.
4. Change USB Port (use USB 3.0)
Prefer ports on the back of desktop PCs, they connect directly to the motherboard.
5. Turn Off Background Apps
Apps like Chrome, OBS, RGB controller software consume CPU cycles.
Close unnecessary apps and try again.
Fix Input Lag on Android
1. Toggle Game Mode / Gaming Optimization
On most Android phones:
Settings → Battery → Performance → Enable Game Mode
2. Turn Off Nearby Bluetooth Devices
Bluetooth controllers share frequency with:
- TWS earbuds
- Smartwatch
- Bluetooth speakers
Turn them off and test again.
3. Remove Controller & Re-Pair
Sometimes pairing cache causes lag.
Steps:
- Go to Bluetooth settings
- Tap controller → Forget
- Pair again
4. Try a USB OTG cable (wired mode)
Wired mode reduces latency to near-zero.
5. Test Input Delay Online
Open on Chrome:

Press a button and check if the button lights up instantly.
Advanced Fix: Lower Bluetooth Latency (Controller Specific)
| Controller | Setting / Fix |
|---|---|
| Xbox Series Controller | Updates firmware over Xbox Accessories App |
| PS5 DualSense | Turn off haptic intensity + adaptive triggers |
| Generic Bluetooth | Shorten distance to phone or PC |
How to Measure Input Delay
You can use the online tester:

If the response is:
- Instant → Controller is fine
- Delayed → Issue is Bluetooth or OS
FAQ
How much delay is normal?
- Wired controller: 0–3 ms
- Bluetooth controller: 20–50 ms
Do cheap controllers have more lag?
Yes. Many generic Bluetooth gamepads use weak transmitters.
Final Verdict
You can eliminate most input lag using:
- Wired connection
- Disable Steam Input
- Reduce Bluetooth interference
